I have an SGpro REv3 with EX·3, and I notice some vigneting and problems to adjust focus in the EX3.
I know some issues can solves with the new achromat and SGBlade, but really how big are the differences between boths achromats?.
Problems of vignetings can solves with the SGBlade or the new achromat?

I,m worried on spend more money on adapters.... instead a DSLR
What do you think?
It´s a good idea to buy a new adapter ( the SGBlade flip) or the new flip with the achromat for EX3?

thanks
 
I would not use the old achromat on an EX-3 . If this is the original SGPro achromat it will be terrible anywhere but the center unless your camera is at f5.6 to f8. on the EX. If its the first generation Blade it will only be poor with lots of CA. The new achromat is great.
If you don't care go ahead and use it.
I can't tell you what the trade-offs are money wise re DSLR or Blade etc. I expect Rev3 should look very good with the new Achromat but don't know how well it works without a flip. That's a good question for Wayne. If the SGPro will work well with the new achromat then you don't really need the advantages of the Blade especially if you are planning to use RR2 anyway and can't stop down the 35mm lens iris.

thanks, Lenny
I,m thinking on SGblade to use rr 01, to have the cleanest and sharpest image possible. I like the bokeh of rr 02, of course.
I Didn,t know the trick of use the EX iris from 5.6 to 8,
thanks a lot for your comments
